|Thread: Boxford AUD|
I would look at joining the Yahoo Boxford owners group as well. There is a wealth of information on there and plenty of files you can view or download including manuals.
|Thread: How effective are phase converters|
One thing that does meed mentioning is that the Transwave Rotarys can also take up a lot of space in a workshop. If space is at an absolute premium then that may well be an important factor as you can get a compressor in a worksop in the space that a rotary will take for example. A VFD takes absolute minimum space.

|Thread: Scam or too good to be True|
Yes, even less on the Myford?
Qualters and Smith Drill
|Thread: Warco GH750/ Chester Cub 630 any good for a hobby machine.|
Martin, we were down at Chester at the beginning of the week for their " Open Week".
They have had a couple of old stock Cub Lathes there that they have had for a long while now.
It may be worth having a chat around what best deal would be if you were interested.
|Thread: Using Chalk to Centre a 4-Jaw?|
Chalk method is good as above
DTI's can be over sensitive when setting things like irregular castings initially and you may well need one with a lot of travel at first but they good as you close in to final true.
Another method is to have a decent plate that you sit on your bed and which extends back out toward the operator ( also used for sitting a mag base and clock on ) onto which you just use a scribing block at first to get the high points closed in. You can get pretty close just using it like this before final clocking if at all needed.
And for anybody reading this new to lathe work, where the material is of a pretty regular profile you can get the work relatively true to start with, just by using the machined grooves in the 4 jaw chuck face to position the jaws as either equal as needed, or offset to suit the outer profile by using as steel rule to measure positioning.
|Thread: Colchester Student 3100 VS|
Yeh, have seen the calcs in earlier posts. At £2300 plus the 39% it still looked a good price, as the lathe looks to be a nice one, but like you mention about the possibility there was large reserve, so no deal.
I have been used to buying for my works in the past, usually from companies that have been in liquidation where most equipment had no reserves, so the only real consideration was the buyers premium. Occasionally the equipment would probably had avreserve where it was still owned by a lease company.
Vat was then not an issue like it is for private buyers. Maybe worth only looking at liquidation sales really.
Anyways Gary, good luck with your search.
Dont forget: The listed prices on their web site are plus 20% Vat
Thanks for the great feedback Gary.
Just missed the final bidding.
Anybody see what it went for pls?
|Thread: casting recommendation|
Another one in the North West for both ferrous and non-ferrous. Used them a lot in industry.
|Thread: Alternative source of industrial drawer cabinets?|
Plus another for Bisley especially if you can get their earlier ones.
I personally do find that the later ones are just not as substantial. They are about fit for pupose in a latter day office but struggle a bit in the workshop for heavier items..
The earlier ones seem to have been well over engineered for office use, hence their suitability for the workshop is very good.
|Thread: Colchester Student 3100 VS|
I live local to the machine tool dealer and know them quite well. When managing the company i worked for, have dealt with them over the years in both buying and selling. Location both in Tameside and when in Oldham. They have always had a decent reputation for buying and supplying good straight machines. Both the machine tool fitter and electrician they use I have also used and which are well respected.
In fact i bought my current M300 ( in my gallery ) from them as a negotiated cash deal. They have always carried a decent supply reputation. They use contractors for transport who obviously are well versed in handling machine tolols and there is always the possibility they could put their contact details your way. I used them to drop my machine off.
Like with all machine tool dealers, a lot depends on where in the purchase to sale the machine is at. By this i mean when they purchase a machine there may well be faults or it may just be good to go. So how far to being suitable for retail in good to go is always the purchasers gamble prior to buying/bidding.
As for the variable speed Colchester Student I cannot comment specifically but only what I know generally about the variable speed models in particular the Harrisons. The Harrison VS330tr which is the variable speed toolroom version of the M300 has been known to be problematic in industry, can be expensive to correct and be far more difficult to convert to 240v inverter control.
I also think you will find that the variable speed Student will have the same dimensions as the Student 1800 for steadies etc. So check that out if successful.
I took a punt when both a nearly new fixed steady and travelling steady appeared on Ebay for the Harrison VS330tr at an absolutely low BIN price and they fitted the M300 perfectly when they arrived - result.
|Thread: Which collet chuck for a Warco GH1236 lathe|
I initialed shared the ER40 set up used for my milling by adding the D1-4 mount chuck on my Harrison M300. It is now just used on the VMC.
I got a great Ebay deal that came up using BIN as it just appeared, on the Pratt D1-4 collet setup which goes up to 38mm. Much better quality than the ER40 system but slower to load and unload. They are great chucks and very positive but they are difficult to get hold of and can command prices up to £500.
|Thread: Removing Chucks|
And should also keep the chuck square the spindle as it comes off. A good fit in the spindle would help.
|Thread: Small Pratt burnered chucks. Jaws?|
Thame Engineering may be worth a call as well.
|Thread: Where (apart from ebay) to look for a pillar drill base?|
An alternative would be to do yourself a half decent drawing and take it to a steel profilers of the dimensions and contour you want/like and have a profile cut from steel plate.
Have it stress relieved and surface ground ground both sides to clean.
You would have little work left to make it usable.
|Thread: Crap vee blocks and "Oxford Precision"?|
Theres a lot of truth in the old saying:
Easy buying cheap tools cheap but buying quality tools cheap is a "science".
I am with Chris Evan6 on his comments in that buying far eastern tools from UK suppliers is the way to go. Taking a chance on import duties and Quality by buying direct, just to save a few quid is dodgy to say the least. Price to return anything is a none starter.
I am pretty sure that the UK suppliers such as Chronos, ARC, RDG, Amadeal, Warco, Chester, ( to name just a few of the more known ones) do in fact carry full QA assessments on their suppliers before putting them on their approved supplier lists.
I know the OP made reference to ARC, but I dont think I read that in any sort of derogatory way, in fact like others, the stuff i have had from them has been spot on for me, in fact comparing to many others i have used both in industry and home, have to say they are up there in the top quartile.
In fact the only real problem i have had in the last 2 or 3 yrs or so were some backing plate raw castings that although looked visually perfect revealed large blow holes ln an important area when machining. These were from RDG being local to me. No problem returning for replacement, just lost time ( but who hadnt experienced this in industry ). No quible and easy. Direct from Asia I would have had to write off.
|Thread: Machine moving day.|
You can't beat having someone with a decent bit of kit andknows how to use it.
The lathe looks perfectly balanced. But dont they just looked lost on the flatbed
|Thread: Got a Good Story About Buying a Lathe?|
Nothing exciting but:
About 30 years ago I managed to get my hands on an old Colchester Master lathe from either Exchange and Mart or Loot, cant remember which. Chuck wise it it was well equiped and the lathe in more than acceptable condition.
As with many quite a few lathes about then, practically all the change wheels had vanished and no steadies.
It took me about 6 months of continually rumaging around in scrap yards trying to build up a full set of the correct DP wheels to eventually build a full set, several being modified by bushing or boring etc. Alternative steadies were sourced, reworked or adapted to suit.
I dont know if this was just was an excuse to rumage and nosey round but it was always so satisfying as usually something else was bought when leaving. Nobody seemed to bother when you explained the mission you were on, you just got a free hand to roam at will. At the time there was a lot bigger choice of yards about, a lot more machine tools, textile machinery, printing equipment, engines etc being scrapped off.
No chance now with H & S controls, plus scrap yards just Ebay some of what comes thru'. I miss that ability to roam free in them for bits. Dont think I have enjoyed equiping a lathe as much since.
